Loud doesn't equal power, flows suck and there is almost no good flowing glasspack. Dynomax ultraflow or a magnaflow muffler would really sound good and still be able to hear yourself think going down the road and not drone the fillings out of your teeth. check You tube for different muffler sounds.

Thrush Magnum glasspacks use a perforated inner tube, not the louvered fiberglass mess that Cherry Bombs use.. There design also produces a much mellower tone. When I refer to Glasspacks, I'm not even thinking of the Cherry Bombs, only Magnums cause there the only Glasspack I use
